The Bloomington Police Chief did not reveal the suspects name but said he was a 24-year-old man who is now in police custody. A criminal complaint from July of 2015 states he was taken into custody after he was seen throwing items from the upper level of the mall to the lower level.
He stressed he believed the incident was "isolated" and said there was no wider threat to the public.
The chaotic scene played out about 10:15 a.m.in the southeast corner of the mall.
Aranda is being held on suspicion of attempted homicide, and police expect to submit the case to prosecutors in support of charges by noon Monday, Potts said. "Bloomington Police is investigating the incident", it said.
Police do not believe there is a relationship between the suspect and the child and the incident appeared to be isolated.
Months later, in October of that same year, he was accused of throwing glasses of ice water and tea at a woman in a restaurant at the mall after she refused to buy him food, the records show.
A woman who works at a nearby store and who did not want to be identified said she heard loud screams, went outside the store and saw the boy hit the ground. Police learned at that time he had an existing trespass notice prohibiting him from the Mall until July of 2016.
Police identified Emmanuel Deshawn Aranda as the man who was chased and arrested after Friday morning's incident at the megamall in suburban Minneapolis.
Witnesses say the boy's mother was screaming and asking others to pray for her son. Mall Security responded immediately as well as the Bloomington Police Department.
A portion of the mall on the first and third levels was cordoned off as police and the Hennepin County sheriff's office crime lab processed the scene. Police said they do not, at this time, believe the man to have been related to the victim.
Potts said he couldn't give an update on the boy's status, except to say that he's being cared for at the hospital and that his parents are with him. Following that incident, he was convicted of obstructing a legal process by interfering with a police officer.
